How much if at all will CCI 450 primers effect a 223 load with 55gr FMJBT using H335 powder versus Winchester standard primers. Do I need to adjust powder charge?
This is for a 16"bbl AR for plinking.

.2 or .3 tenths less powder sounds about right, if anywhere close to max loads drop back more than that and workup again
lf the saying "Liar, Liar your pants on fire" were true
Mainstream news might be fun to watch

Thanks. That is what I was thinking as well. I think max for the H335 is 25.3. Will probably drop .6 and see how that does.
